Development of Online Lessons with Problem-based Learning on Computational Science for Mathayom 4 Students at Ban Rai Witthaya School

Abstract

The objectives of this research was to: 1) development of online lessons with problem-based learning on computational science for Mathayom 4 students at Ban Rai Witthaya School 2) compare the academic achievement of students before and after online lesson using problem-based learning, and 3) assess students' satisfaction with the online lesson. The sample for mathayom 4 students 30 students at Ban Rai Witthaya School selected using simple random sampling.The research tools included a learning management plan, an online lesson using problem-based learning, a learning achievement test, and a student satisfaction questionnaire. The statistical methods used were mean, standard deviation, and t-test. The results indicated that: 1) the developed online lesson consisted of three units, 1. Computational thinking 2. Problem solving and algorithms 3. Project development the content quality was rated at the highest level (x ̅ = 4.70, S.D.= 0.20)and the production technique quality was rated at the highest level (x ̅ = 4.72, S.D.= 0.21), 2) students' post-learning achievement scores were significantly higher than pre-learning scores at the .05 significance level, and 3) students' overall satisfaction towards online lesson usingproblem-based learning was rated at the highest level (x ̅ = 4.62, S.D.= 0.44)
